Ribosome profiling is a method based on deep sequencing of ribosome-protected mRNA fragments. Purification and sequencing of these fragments provides a “snapshot” of all the ribosomes active in a cell at a specific time point. This information can determine what proteins are being actively translated in a cell.
Ribosome profiling enables systematic monitoring of cellular translation processes and prediction of protein abundance. Determining what regions of a message are being translated can help define the proteome of complex organisms. In combination with massively parallel Illumina high-throughput sequencing, ribosome profiling allows detailed and accurate in vivo analysis of protein production.
Identify transcripts undergoing translation for visibility to an important aspect of gene regulation.
Ribosome profiling uses size-exclusion chromatography. This method streamlines the steps to convert ribosome-protected RNA fragments into libraries compatible with sequencing on Illumina instruments. It is a simple, rapid, and scalable method that does not require special equipment. In contrast, other methods to isolate polysomes and monosomes rely on several hours of ultracentrifugation using either a sucrose gradient or a cushion.
Flexible power. Speed and simplicity for everyday genomics. 7–20 ribosome profiling samples per run.
